SATURATION APPARATUS.

Serial No. 681,258.

To all whom it may-concern:

- Be it known that l, lVniLnxM Futons, a subject oi the German Euuieror,residing at Bloomfield, in the county et' Essex and State of New Jersey,have invented new and useful Improvements in Saturation Apparatus7 ofwhich the followingis a'speciication.

The object of the present invention is a saturation apparatus mainlydesigned to carry on the process in which gases ot' difterentcompositions are ,separately passed through the same saturation bath andseparat-ely withdrawn from the latter.

The apparatus under consideration further employs novel features ofconstruction hereinafter shown and described, to the end of improvedresults of operation. 'v

The invention will be best understood by reference to the accompanyingdrawing in which;

Figure 1 is ay vertical section through a saturation apparatusaccording: to my invention.A Fig. 2 is a horizontal section on the linesA--B of Fig. 1, while Figs. 3 vand l represent developments of the lowerends ot parts 12 and 17 respectively.

0n. the drawing` 1. represents a vessel of circular cross section andpartly illed with a saturation liquid. lt the production oi ammoniumsulfate is intended the saturation liquid consists of sulfuric acid or`an acid salt solution. The bottom ot -vessel 1 is tapered downward tocollect the precipitated salt, which is either continuously or atintervals removed by the ejector 2. The cylindrieal portion of thevessel is provided on the inside with a helical annular rib orprojection 3. Vessel 1, which itseliil is open at the top, isA envelopedby a housing or casing.

4t, the top part ot which is formed by a re- Between vessel 1 andhousing` l an annular space or chamber G 'is formed, communicating abovewith the ves-` sel and through which hot rases issuing :trom the `latterare passed. The bot-tom of 7 supporting vessel 1, and agas outlet 8. 1nthe lower part ot'- housing 4 an annular pocket S) is formed in whichany condensates formed by the gases are collected. Cap 5, .is providedon the inside with a. cylinder `1() formed from depending walls of saidcap the lower ,ends `of *which project.-into the satura-tionl liquid.preferably con centric `with vessel 1. At the upper end.,cylinder1*()yis equipped with a gas inlet 1K1. Inserted 'into cylinder 10 is a secondcylinder or bell `1'2 supported at its upper end by iiange 13,V whichalso serves to close the insertion opening provided in cap Bell 12which, together with cylinder 10 forms the annular chamber 14 projectssomewhat deeper into the liquid than cylinder 10 to 'form a, guard formaintaining different gases separately in the' acid bat-h and serving toguide them in their proper channels. Chamber 14 is pref-` erablyconcentric with chamberl 6. .The lower end or" bell 12 is provided onits'outside with a number of short ribs or the `like 15 so arranged asto ascend on the outer surface of the bell. The ribs or projections l5close annularly with a suitable clearance against the inside'o cylinder10. The inside of bell 12 is provided in a` similar manner to vessel lwith a spiral like annular rib or projection 16. Extending within bell12 is apipe 17 provided at its upper end with a gas inlet 18. This pipedips into thev liquid to about the same depth as cylinder 10. The lowerend of pipe 17 is provided similarly to bell 1:2 but on its inside witha series of short ribs or projections 19 so arranged vas to ascend onthe inner` surface of the pipe.v Ribs 19 close annularly with suitableclearance against the ejector pipe 2. The upper part of bell 12 isprovided with a gas outlet 20.

The operation is as followss-Gases ar conducted to annular chamber 14 bythe inlet11. These gases leave chamber 14 through the ducts formed bythe inclined ribs 15v and the, various streams of gas being thustangenti-ally deflected inbreaking through the 'liquid cause the latterto assume a continu.-

ous rotary motion. The gases afterpass- Patented May 27,1913.v

ing through the liquid collect in the top part of vessel 1 and from hereare conducted through annular chamber 6 and -ledaway` by outlet. By thismethod of withdraw-` ing the het gases from the saturation vessel theradiation of heat from the latter is greatiy reduced and at the sametime considerable cooling of the hot gases peiected.Y

Any condensates formed by the gases in passing through .chamber 6 arecollected in the annular pocket? I9 and let oit' by pipe 21.

Simultaneously gases are conducted to pipe 17 by inlet 1 5 and passedthrough the liquid by the ducts formed by ribs 1 9. These 1 gases inbreaking through the` liquid are de- ;lected, in the. Isame dlrection aslthe vgas passingthrough chambre-1314, so that 'an additional torque isproduced. All parts of the liquid are therefore kept Well in circulatorymotion and by the additional aid of the helical ribs )Sand 16 which, inrotating the liquid produce a continuous up and down movement` of thesame, a thorough mixing of the bath` and a constant acidity andtemperature in all parts of same is assured. The gases after passingthro-ugh the bathare collected 1n the top part of bell 1:2

and led away by pipe 20. The salt collect-` l for supplying gas to eachof said annular `chambers and'independent means for withdrawing suchgases from ysuch chambers after theyhave passed 1n Contact with theliquid.
